Diet pills linked to increased kidney damage Add to ...

There's more bad news for people relying on pills to lose weight.

Canadian researchers, led by Matthew Weir of the University of Western Ontario, discovered an increase in kidney damage among patients taking the weight-loss drug orlistat, sold under the brand name of Xenical.

Using Ontario health data, they found that 0.5 per cent of patients prescribed the drug were hospitalized for kidney problems in the year prior to treatment. That hospitalization rate rose to 2 per cent after patients had been on the drug for a year, according to the results published in Archives of Internal Medicine.

The researchers suggest patients prescribed orlistat should be closely watched for kidney problems.
